What exactly happens to light in a black hole?

Light is not immune to gravity, although a photon at rest does not have mass, but a moving photon will produce a moving mass, which will be affected by gravity. For example, the redshift of light, as well as the effect of gravitational lensing, are all manifested by the gravitational force of light. Einstein's theory of relativity is that it is not allowed to have superluminal matter, but there can be superluminal virtual images, for example, when it is cloudy, the searchlight has a large spot on the clouds, even if the light source below has a little movement, the upper spot will move at a very fast speed, assuming that the height of the cloud is high enough, the speed of the spot can move faster than the speed of light, this is because in the process of moving the spot, there is no energy transfer, So faster-than-light is permissible under certain conditions.

Since Einstein's general theory of relativity cannot be perfectly combined with Planck's quantum mechanics, it is impossible to say that Einstein's general theory of relativity is completely correct, and finding the error is a major problem facing scientists at present.

There is a scientific concept called density, i.e., the actual radius and the Schwarzschild radius, which indicates the degree of distortion of space.

White dwarfs are only 1/10,000th the density of black holes, and the spatial distortion caused by them is of course much smaller.

The reason why there are such questions is because it is good to read and not to seek solutions.

Gravitational force is a manifestation of the curvature of space-time. In general relativity, the law of gravitation fails, that is, the law of gravitation is only valid in Newton's space, and must be corrected when the curvature of space-time is obvious, which is why one can prove the general theory of relativity correct by observing the perihelion motion of Mercury.

Outside the event horizon of a black hole, matter or light can escape, and within the event horizon, neither matter nor light can escape. If the "surrounding stars" are far away from the black hole, they will certainly not be sucked in.

In general, black holes are much more massive than white dwarfs. The largest black hole has 15 trillion solar masses, and white dwarfs cannot have a mass greater than one solar mass. But in the final analysis, the curvature of space-time is not just about mass.

Rubber wrap is often used as a metaphor for space. If a copper ball and a wood ball of the same mass are placed on top of the tensioned rubber film, the curvature of the film near the copper ball will of course be greater. Even if a black hole has a mass smaller than a white dwarf, the curvature of space-time around it is still greater than that of a white dwarf.

Faster-than-light does not exist. When the speed of an object with respect to us is the speed of light, its time is stationary with respect to us. Of course, the only particles that can reach the speed of light are particles with zero mass.

Matter does not disappear after entering the black hole, and the mass remains. The center of the black hole is the singularity. Matter there is not a collision, but a more drastic change occurs than the collision.

But to understand the situation of the singularity, general relativity is also not enough. We look forward to a breakthrough in string theory.

Research believes that if human beings fall into a black hole, it is equivalent to experiencing a terrible "torture", of course, although very terrible, but the time of this "torture" is extremely short, and the whole process may be shorter than the blink of an eye. In other words, when you fall into a black hole, you may not have reacted back, and you may have been torn apart by the huge gravitational pull of the black hole, and your body is twisted at the same time. ”

Modern scientific research suggests that black holes are not the only way to form, for example, massive stars will form stellar black holes at the end of their lives by supernova explosions.

In addition, primordial black holes are also formed by gas and dust in the early universe, and the current known types of black holes in the universe also include supermassive black holes and intermediate-mass black holes.

It seems that humans have a comprehensive understanding of black holes, but in fact they are not, because black holes do not emit light, which also led to the concept of black holes after Einstein proposed the concept of black holes, and it was not until recent years that humans successfully photographed the first black holes**.

The main reason why people can't see black holes is that people can't make such devices at all. My understanding is that the interaction of forces is done by the mutual interference of waves, not by emitting some solid matter.

The formation of the interaction mode of microscopic particles, that is, the formation of waves is caused by the regular movement of magnetic particles, people know that the degree of interference between waves of different frequencies and wavelengths is different, some interfere, some do not interfere, then the problem comes, people know that the smallest unit that makes up the world of matter is the atom, the wave emitted at the atomic level is caused by the regular motion of the magnetic particles that compose it, and the wave emitted by the magnetic particles that are smaller than the magnetic particles that make up the atom are in the state of existence, It doesn't interfere with the waves emitted by devices that people can build, which is why people can't observe black holes.

That's what I guessed, black holes have their meaning in the universe, probably these possibilities.

One, black holes are the entrance to the envy of the universe in another dimension. What it sucked and devoured did not disappear, but was forced by the black hole to move to a new realm, and there is no way to know what the situation was, but at least it was different from the current universe.

Second, black holes are the "sweepers" of the universe. Its mission is to remove all matter and energy from the universe, and to turn the universe into another form of universe. This may be another way of changing the universe.

Third, the black hole is shrinking and sucking the universe until it gets smaller and smaller into a singularity. We feel that the universe is expanding, even infinite, and black holes are swallowing matter and space all the time, and everything is adducted, and we are just not aware of it.

Fourth, a black hole is a "reservoir" or "remodeler". It inhales energy and matter, stores and preserves, and new matter and energy are born in the universe; Or something that is inhaled, processed by a black hole, and then reborn somewhere in the universe.

Black holes should be a fact of objective existence, just like the existence of the earth in the universe is the same, maybe he is a cleaner in the universe, maybe he is, a driving force to balance the universe, maybe he is an engine of the entire universe, so its existence must have its meaning of existence, with the development of human science and technology capabilities, after all, one day human beings will rely on their own intelligent brains to unveil the mystery of black holes.

Black holes are the engines that keep the universe running.

There must be all rotational motion"Black holes", a small vegetable sink when there is water"Black holes", the greater the rotational motion force"The larger the black hole, the greater the devouring power, not to mention the Milky Way.

Because God has not yet fully occupied the universe, there are still a few Satan who have become black holes to cause trouble.

The heart of the energy conversion of the galaxy is closed, and the black hole is similar to the heart in our body in this cosmic system. In fact, the Chinese ancestors left the schematic diagram of its mechanism to mankind more than 5,000 years ago. The Taiji diagram is the source diagram of the complete cosmic working fluid modeling.

The more the research does not understand, the more unclear, the science cannot falsify, the things and phenomena of ultra-long distances and distant years, the appearance of "understanding people" suddenly increases, and even a person who has just become Chinese has become the level of a scientist.

Black holes are in line with my "Spreading Pancakes Out of the Universe Theory". After a long time of pancake stalls, a black hole will come out.

The upstairs statement is completely unreliable. The nearest known black hole to us is also 1,600 light-years away. Isn't it 3,600 years to wait for the rays we send out and so on to receive them back?!

This is just the most recent discovery. So it's not like that. The discovery of black holes is mainly based on the observation of "gravitational lensing".

Due to the strong gravitational pull of a black hole, light passing through its vicinity creates refraction. It works just like our common convex lens. So there are some weird arcs of light around the black hole.

We found out that black holes exist by analyzing these arcs. The attached image shows a very complete gravitational lensing arc captured by the Hubble Space Telescope. Obviously, it has a very massive black hole in the middle.

Because the black hole is a void formed by a pure spiritual matter, this hole can "attract" all kinds of material particles (fields) of the outer material protective layer of the solar system to its top, that is, the outside of the universe, under the action of supermass, a predictive field will be generated in front of it, and it can manifest objects and things that may appear on the surface in a few months or even years later, such as natural phenomena such as mirages are the ,...... he createdTherefore, standing on top of a black hole, you can see any corner of the earth day and night, and you can also see all corners of the solar system,......Its function is similar to that of a matter telescope and a telescope of predictive fields, ,......As we all know, there are three types of parallel substances found now: matter, spiritual matter, supermass, etc., all kinds of stars outside the solar system are composed of pure spiritual matter, and all stars within the solar system (including the earth) are composed of spiritual matter and matter, and there is a protective layer on the periphery of the earth, and there is also a protective layer of material on the periphery of the solar system, that is, the material protection "shell" ,...The recently discovered black hole simulation of the Vega Galaxy is actually a simulation of the interaction between the solar system's protective layer (shell) and ,......the black holeAs we all know, paralleloplasms generally do not interact directly with each other, unless the supermass creates a force field effect, etc., for example, there is no direct interaction between pure matter and pure spiritual matter, so the solar system and its peripheral stars are detected by instruments and meters of various pure substances, ,......which is extremely distant, and so on, and so onBecause the black hole "attracts" all kinds of light wave particles to the outside of the universe, that is, above the telescope, what is seen is a "black hole" ,...

We can't see black holes, we know that they exist because everyone revolves around them, black holes are ultimate stars, not a hole, and the name comes from the fact that the holes do not reflect any light, so the blackest is called a black hole.

That's through indirect means, not to see the black hole, and when matter falls into the black hole, the matter will be transformed into pure energy and radiated out. The gravitational pull of a black hole can also have an effect on surrounding stars, such as the famous Cygnus X-1 ray source.

We can't see black holes. Because the density and gravitational pull of a black hole are so great that even light cannot escape its surface.

However, we can suspect the motion of a celestial body to infer the presence of a black hole around it. If the suspect object is in a spiral motion and it is disappearing, and there is a gamma-ray burst around it, then we consider the suspect object to have a black hole around it; Conversely, we can assume that there is no black hole around the suspicious object.

We can't see black holes. We use an instrument to understand black holes. This instrument emits light. When a black hole absorbs this light, it releases (gamma) rays. Here's how we understand it.

We can't actually see a black hole because it's a white starlight in the background, and it's black.

In fact, most of the black holes are seen due to gravitational lensing effects and ray detectors.

Stephen Hawking once said: Black holes are not black.

In 1916, the German astronomer Karl Schwarzschild calculated a vacuum solution to Einstein's gravitational field equation, which showed that if a large amount of matter is concentrated in a point in space, a strange phenomenon will occur around it, that is, there is an interface around the particle point - once the "event horizon" enters this interface, even light cannot escape. This "incredible celestial body" was named a "black hole" by the American physicist John Archibald Wheeler.

Black holes cannot be directly observed, but their existence and mass can be known indirectly, and their effects on other things can be observed. Information about the existence of a black hole can be obtained by using the "edge information" of the rays emitted by the high heat before the object is sucked in. The existence of black holes can also be inferred by indirect observation of the orbit of stars or interstellar clouds.

On December 7, 2017, scientists at the Carnegie Institute for Scientific Research in the United States discovered the most distant supermassive black hole ever recorded, with a mass 800 million times that of the Sun.

A black hole is a type of celestial body in the universe in modern general relativity. The gravitational pull of a black hole is so great that the escape velocity within the event horizon is greater than the speed of light.

A black hole is a singularity with infinite density, infinite curvature of space-time, infinitely small volume, and infinite heat in the center, and a part of the surrounding empty celestial region, which is not visible within the scope of this celestial region. According to Albert Einstein's theory of relativity, when a dying star collapses, it will gather into a point where it will become a black hole, swallowing all light and any matter in the adjacent cosmic region.

A particularly dense dark object predicted by general relativity. Massive stars collapse at the end of their evolution, and their matter is so dense that it has a closed boundary called the "event horizon", and the black hole hides a huge gravitational field that is so strong that any matter, including photons, can only enter and cannot escape. The lower limit of the mass of the nucleus of the formation of a black hole is about 3 times the mass of the sun, which, of course, is the mass of the last nucleus, not the mass of the star in the main sequence period.

In addition to this stellar black hole, there are other black holes - the so-called miniature black holes may have formed in the early universe, and the so-called supermassive black holes may exist in galaxies**. (Reference: New Horizons of the Universe).

With the American "Chandra" X-ray space telescope.

Black holes have "stealth" technology, people cannot directly observe it, and even scientists can only put forward various conjectures about its internal structure. So, how do black holes hide themselves? The answer is curved space.

We all know that light travels in a straight line. This is the most basic common sense. However, according to the general theory of relativity, space bends under the action of a gravitational field.

At this time, although the light still travels along the shortest distance between any two points, it is no longer a straight line, but a curve. Figuratively speaking, it seems that light was supposed to go in a straight line, but the strong gravitational pull pulled it away from its original direction.

On Earth, this bending is negligible due to the small action of the gravitational field. And around a black hole, this distortion of space is very large. In this way, even if some of the light emitted by a star blocked by a black hole will fall into the black hole and disappear, another part of the light will pass through the curved space around the black hole and reach the Earth.

So, we can effortlessly observe the starry sky on the back side of the black hole, as if the black hole does not exist, which is the stealth of the black hole.
